BRIMFIELD – A 79-year-old man was killed in a one-car accident Monday evening.

The driver was heading east on Route 20, also known as Palmer Road, at about 4:30 p.m. when he hit the soft soil at the side of the road. He overcorrected and ended up crossing the road and driving up an embankment that separates the two sides of the road and then hit the guardrail, Brimfield Police Chief Charles T. Kuss said.

The car then rolled over and slid down into the eastbound lanes. It is not known if the driver was wearing a seat belt, he said.

The driver, who was alone in the car, was rushed to Wing Memorial Hospital in Palmer by ambulance. He was treated at the hospital but later died, Kuss said.
